From the front as well as from behind - well, absolutely flat woman. Only one advantage is obvious - well-designed orifices. And of course due to the flat buttocks it's very convenient to pull your partner in the anus, even without bending her over. And I don't see anything else interesting in this lady! The man is basically of age, so probably the determining parameter for him is the age of the woman and the possibility to work her anally!
Great student, passed the exam with flying colors. Taking advantage of her gorgeous forms, she seduced the instructor, and he could not resist. First gave him a beautiful blowjob, then saddled him.
